geom_ribbon removes missing values
Hi everyone,
it looks like geom_ribbon removes missing values and plots a single
ribbon over the whole interval of x values. However, I'd rather want it
to act like geom_line, that is, interrupt the ribbon for the interval of
missing values and continue once there are new values. Here's an example:
library(ggplot2)
df <- data.frame(
date = seq(from = as.Date("2010-05-15"),

Defining a viewport scale in {Grid}
Am just feeling my way into the grid library, and cannot figure out how to
define the plot limits. 3/5 of the example polygons below plot in the
default 0-1 range viewport. But when I try to redefine the viewport the
polygons plot in the same places. I also get the same result without
employing push/pop. (As you can see from the scale I'm trying to introduce,
I want to plot map polygons.)
